POWER AMPLIFIER (PA) SYSTEM WITH ELECTROTHERMAL FEEDBACK CIRCUITRY FOR PA GAIN CORRECTION |
| 摘要 |
A power amplifier (PA) system with PA gain correction is disclosed. The PA system includes a PA having a bias voltage input; and electrothermal feedback circuitry coupled to the bias voltage input. The electrothermal feedback circuitry is configured to receive thermal feedback generated by the PA and maintain a substantially constant PA gain by automatically changing a bias voltage level at the bias voltage input based upon the thermal feedback. |

1. A power amplifier (PA) system with PA gain correction comprising:
a PA having a bias voltage input; and electrothermal feedback circuitry coupled to the bias voltage input and configured to:
receive thermal feedback of the heat generated by the PA; andmaintain substantially a constant PA gain by automatically changing a bias voltage level at the bias voltage input based upon the thermal feedback. |
